|101-0158-01L||Method of Finite Elements I||4 credits||2G||E. Chatzi, P. Steffen|
|Abstract||This course will introduce students to the fundamental concepts of the widely established Method of Finite Elements including element formulations, numerical solution procedures and modelling details. The course will also equip students with the ability to code algorithms (largely based on MATLAB) for the solution of practical problems in Infrastructure and Civil engineering.|
|Objective||The Direct Stiffness Method is revisited and the basic principles of Matrix Structural Analysis are overviewed.|
The basic theoretical concepts of the Method of Finite Elements are imparted and perspectives for problem solving procedures are provided.
Linear finite element models for truss and continuum elements are introduced and their application for structural elements is demonstrated.
The Method of Finite Elements is implemented on practical problems through accompanying demonstrations and assignments.
|Content||1) Introductory Concepts|
Matrices and linear algebra - short review.
2) The Direct Stiffness Method
Demos and exercises in MATLAB & Commercial FE software
3) Formulation of the Method of Finite Elements.
- The Principle of Virtual Work
- Isoparametric formulations
- 1D Elements (truss, beam)
- 2D Elements (plane stress/strain)
Demos and exercises in MATLAB & Commercial FE software
4) Practical application of the Method of Finite Elements.
- Practical Considerations
- Results Interpretation
- Final Project where a Real Test Case is modelled and analyzed

|3 credits||4G||E. Chatzi, P. Koumoutsakos, B. Sudret|
|Abstract||The course presents fundamental concepts and advanced methodologies for handling and interpreting data in relation with models. It elaborates on methods and tools for identifying, quantifying and propagating uncertainty through models of systems with applications in various fields of Engineering and Applied science.|
|Objective||The course is offered as part of the Computational Science Zurich (CSZ) (http://www.zhcs.ch/) graduate program, a joint initiative between ETH Zürich and University of Zürich. This CSZ Block Course aims at providing a graduate level introduction into probabilistic modeling and identification of engineering systems. |
Along with fundamentals of probabilistic and dynamic system analysis, advanced methods and tools will be introduced for surrogate and reduced order models, sensitivity and failure analysis, parallel processing, uncertainty quantification and propagation, system identification, nonlinear and non-stationary system analysis.
|Content||The topics to be covered are in three broad categories, with a detailed outline available online (see Learning Materials).|
